Embodiment Construction
[0019] refer to Figure 1 to Figure 6 As shown, the AB glue dispensing machine of the present invention is composed of a set of plunger type glue dispensing valve 100, a set of mechanism 200 for precisely controlling the amount of glue, and a set of mechanism 300 for quickly replacing the mixing tube and needle.
[0020] The plunger type glue dispensing valve 100 includes two separately separated cavities, respectively A glue temporary storage cavity 611 and B glue temporary storage cavity 612, each cavity has a rotary switch valve 60, and the switch valve 60 is provided with a glue inlet 601, a glue outlet 602 and an air filling port 603 that are connected to each other. At the glue port 602, the two switching valves 60 rotate simultaneously to switch.
[0021] The plunger type dispensing valve 100 has two working states, which are the glue feeding state and the glue discharging (glue dispensing) state. In the glue feeding state: the two rotary switching valves 60 correspon...
